PATENT "ILLIAM BARTHOLOMENV, OF DOULTON S SANITARY ENGINEERING WORKS, ALBERT EMBANKMENT, COUNTY OF SURREY, ENGLAXD.

WATER-WASTE PREVENTER.

SPECIFICATION forming part of Letters Patent No. 288,758, dated November 20, 1888 Application filed October 9, 1859.. (No model.) Patented in Eng and May 1T,18l,1\'0.9,147.

In all whom it may concern.-

Be it known that 1, WILLIAM BARTHOLO MEW, a subject of the Queen of Great Britain, residing at Doultons Sanitary Engineering Works, Albert Embankment, in the county of Surrey, England, have invented certain new and useful Improvements in ater-Waste Preventers. (for which I have received Letters Patent in Great Britain No. 2,147, dated May 17, 1881,) of which the following is a specification. This invention has for its object improvements in water-waste preventers, and is applicable to prevent waste of water in supplying water-closets and draw-off cocks of any kind, where it is desired that a certain measure of water should be delivered at each actionof the apparatus, and that no more should pass until the apparatus is again started by an external impulse.

The'apparatus consists of a cistern of a capacity to contain the measure of water to be delivered at one time. It is provided with a balhcock, to fill it from another cistern or from the main. An overflow may also be fitted, which, however, comes into use only if the ball-cock should get out of order. The delivery to the closet or draw-off is by a widemouthed funnel, connected through the bottom of the" cistern with the delivery-pipe. This funnel has its month just above the water-level in the cistern, so that while the apparatus remains at rest no water can pass down it. Under such circumstance the cis tern fills and the ball-cock closes when the water in the cistern is still below the mouth of the funnel. The funnel is covered by a bellshaped vessel, extending neagly but not quite to the bottom of the cistern, and the mouth of is attached to the shorter overhanging arm of the lever, so that this may be sharply pulled down when the water should be delivered. The effect of this operation is to raise the water contained in the bell and cause itto'overflow the wide mouth of the funnel on all sides. This water, flowing down into the deliverypipe, establishes a siphon-like action, and the flow once started does not stop until the cistern is empty, or nearly so. The flange at the bottom of the bell is turned up around its inner edge, so that it may contain a certain amount of water, which, acting as a weight, aids the return of the bell. The flange also aids in lifting the water when the bell is drawn up or, in place of partially closing the bottom of the bell by a fixed inwardly -projecting flange, the bell may be provided with movable valvular bottom.

Vhen the apparatus is used in connection with a water-closet having a movable seat, the depression of the seat may be caused to raise a weight, which, when the seat becomes free to rise, descends, and in so doing lifts the bell suddenly, and so sets up the siphon-like action. An afterflow may be obtained by providing a receiverin connection with the delivery-pipe. This receiver fills with the first rush of water, andslowly empties itself again by a small hole into the delivery-pipe, so that the pan of the closet is not under any circunr 7 5 stances left without water.

For flushing drains the action of the apparatus may be rendered automatic, the bell being raised by a weight, which is liberated by a float when the cistern is full.

In order that my said invention may be most fully understood and readily carried into effect, Iwill proceed to describe the drawings hereunto annexed. V

Figure 1 is a vertical sect-ion of a waterwaste preventer constructed according to my invention, and suitable for use to supply a water-closet. Fig. 2 shows a similar arrange ment, except that the bell is provided with a loosely-fitting movable bottom. Fig. 3 shows 9 the apparatus arranged to work automatically from the seat of a closet. Fig. 4. shows the apparatus with additions to obtain an afterflow. Fig. 5 shows the apparatus in a form suited for flushing drains. Fig. 6 shows the bell detached and of modified construction. Fig. 7 shows the movable bottom of the bell detached.

f and depressing the bell e.

a a is a measuring-cistern of a capacity adapted to the discharge which it is desired to obtain.

12 is the ball-cock by which the cistern is supplied. I

c is an overflow-pipe to carry of leakage in case the ball-cock should get out of order.

01 is the funnel-mouth of the delivery-pipe. It stands above the high-water level of the cistern.

e is a lifting-bell covering the funnel d. It is suspended from a lever, f. By a wire connected at f the lever is caused to lift the bell to set the apparatus in action." The bell e is flanged inward at 6, so as to contract its mouth. It is thus rendered more efficient to carry the water up with it in rising. The bell being briskly raised, lifts the water mechanically until it overflows the funnel d, and the flow thus resulting down the delivery-pipe sets up the siphon-like action, which empties the cistern a. The flange 6 also retains a certain amount of water, which, when the cistern is empty, serves as a weight, and aids in bringing the bell down. Blocks are provided, on which the bell rests at a short distance from the bottom of the cistern, such that the water can freely enter the bell at the bottom.

A passage e may be provided to admit air to the bell just before its mouth becomes uncovered, and with this addition the apparatus works silently. This passage admits air to the bell and arrests the siphon-like action before the mouth is uncovered.

In Fig. 2 the bell is provided with a looselyfitted movable bottom, 6 which has a valvelike action, lifting to admit water into the bell, but closing against the passage of water out from it. In this arrangement the funnelmouth stands above the top of the cistern as the loose bottom increases the lifting-power.

. In Fig. 3 the seatof a closet when depressed thrusts the rod 9 upward, lifting the weight WVhen the seat of the closet is free to rise, the weight f falls, lifting the bell and causing the delivery of the water, as already described.

Fig. 4 shows the apparatus with the additions which I make with a view to obtain an afterflow, or the slow discharge of a small quantity of water after the main rush is past. This afterflowv will serve to fill the basin of a valve-closet.

It will be seen that there is a small receiver, h, beneath the bottom of the main cistern a, which receives and retains for a timea part of the water rushing from the cistern a; but it gradually runs into the delivery-pipe by an aperture at h. A valve may also be provided, as is shown at i, attached to the bell and lifting with it. Such a valve serves to limit the main flow to the time during which the lever Fig. 5 shows the apparatus in aform suited for flushing drains, and to obviate the waste resulting from flushing drains by .opening service-cocks and other methods at present in use. The measuring-cistern a in this case is supplied by aslow continuous flow by a tap or otherwise. Meanwhile the bell 6 remains down, the weighted end of the lever f being supported by a finger, 70, upon an axis, is. The axis It carries a pinion or toothed are gearing into a similar pinion or are upon the axis Z. m is a ball-lever, also fiXedto the axis Z. The ball floats up with the rise of the water, and by turning the pair of axes gradually depresses the finger until the end of the lever f slips off from it. The weight then raises the bell, the siphon-like action is established, and the drain is effectually flushed by the sudden discharge of the whole contents of the cistern. The finger 7c is jointed, so that it offers no impediment to the end of the lever f passing to its upper side, which it does immediately, for the suction at once depresses the bell and the outflow of water causes the finger to rise.

Having thus described the nature of my said invention and the manner of performing the same, I would have it understood that I claim as my improvements in water-waste preventers 1. The lifting-bell with the inwardly-projecting flange, in combination with the measuring system, the supply-pipe with its ballcock, and the delivery-pipe having the funnelmouth, substantially as and for the purpose hereinbefore set forth.

2. The lifting-bell c, with the movable or valvular bottom 6 in combination with the measuring-cistern, the supply-pipe with its ball-cock, and thedelivery-pipe d, havingthe funnel-mouth, substantially as and for the purpose hereinbefore set forth.

The combination of the cistern a, the water-supply pipe, the delivery-pipe cl, having the funnel-mouth, the bell 6, having the movable or valvular bottom, the weighted lever f, and the ball-leverm, the whole constituting an automatic flushing apparatus, substantially as described.
